I'm a middle of the road fan of Mad Mex (see my review of the Robinson location if you'd like for more details), but wanted to provide a review based on the location and ambiance of this branch of the restaurant.
Short answer, it may be the worst Mad Mex location and here's why:
The restaurant is consistently too cold, winter or summer
Dim lighting through the restaurant (not in the good ambiance sort of way) or blindingly bright where the only window is located
Super awkward seating (first you get to brush your butt past your table-neighbor's face when you sit down, then it is your turn to show you theirs when they leave!) that is too close together
Difficult to get a parking spot in the neighborhood
I hate to sound picky, but it is true that when you can't feel comfortable in an environment it is likely that you won't enjoy yourself, and that is exactly what happens to me every time I have no choice but to eat at this location. Try one of the many other locations for a better experience if you can!
